| "Event description: On 2/9/01 a fire occurred in a dust collector while |
| torch cutting operations were ongoing. The dust collector is located in an |
| area of known contamination. The individuals present were wearing |
| respiratory protection and full anti-contamination clothing as required by |
| the Radiation Work Permit. When the employees noticed smoke coming from the |
| air filter bank (dust collector), they shut off the ventilation pump drawing |
| air through this particular bank and as a result the fire extinguished |
| itself without adding water or any other extinguishing media. The Oak Ridge |
| Fire Department responded and took hoses in the area but did not use them. |
| The dust collector feeds directly into the main building ventilation |
| pre/HEPA bank that was NOT impacted by this event. The main bank was |
| isolated, opened, and determined not to have been affected. MSC has two |
| parallel pre/HEPA systems for the main building thus allowing them to shut |
| down and isolate one system while the other is online and functional. The |
| housing for the dust collection system was not damaged. There were no |
| personnel contaminated as a result of this event. The workplace air samplers |
| were pulled and determined not to exceed 20% of a DAC for the most |
| restrictive isotope being handled, which in this case was Uranium-238. The |
| building was evacuated a result of the event. The prefilter had been |
| replaced in this unit approximately three days prior to the event. There was |
| damage to the prefilter. DRH staff are onsite investigating the event. These |
| events do not pose a threat to public health and safety, but may be |
| reportable under 1200-2-5-141(2)(c)4 of State Regulations for Protection |
| Against Radiation." |
